Dear Mr. Vinay , please don't get angry . Forget MZP-LKO Corridor . But aren't the other 2 superfast corridors connecting Gomoh - Patna Saheb & Dankuni - Panagarh possible ?? After all , many "Normal Superfast" & "Duronto" Trains can use these new lines to travel congestion free from Calcutta to North India (Punjab , UP , Uttrakhand and J & K) . Gussa mat kareye . Sir , agar aap aise naraz ho jayenge toh phir hamari queries known solve karega . Thank you .
